My wife is a Primary school teacher, and they have recently aquired a Canon
Ion (digital still video) camera for use with their Acorn Archimedes computers.
The set-up they have is the camera, the video output of which goes into a
digitizer which is connected to the machine's expansion port. They are running
some (pretty basic) digitizing software, and getting less than brilliant
The problem I have is that this system seems to me fundamentally flawed. The
camera is digitizing an image, then it is being piped down the cable as analog
video only to be digitized again. If the information could be transferred from
the camera to the computer digitally the results would be infinitely better.
I have also seen a 'kit' for PC or Mac, consisting of the camera, a card to
plug into the computer and associated software. I have not been able to
determine whether the card is simply a digitizer (ie ther same set-up as with
the Archimedes), or some interface allowing digital transfer of the information
from the camera. A third option is that it somehow allows the computer to
access the 2" floppy disks, either by providing a disk drive or using the drive
in the camera.
Can anybody shed any light on how these systems work? Are they re-digitizing a
video signal or is there a better way of doing things? Any info, suggestions or
references gratefully received!
